somewhat personal experience about this.... i was gonna buy an 02 wrx owned by a dealership they soposedly put over 10k in sti and prodrive parts into the car.... someone else bought it about a week...

Ive searched on this and cant find anything... This morn i was late for work and low on gas, so i broke a few speed laws getting to the gas station, while pumping gas i noticed a realy strong burning...
